Description

Technical Field

[0001] This utility model relates to the field of scaffolding pedal technology, and in particular to an anti-slip scaffolding pedal locking device. Background Technology

[0002] In the construction industry, scaffolding is widely used as a temporary support structure for high-altitude operations. Therefore, ensuring the stable placement of scaffolding planks is crucial for construction safety. Traditional scaffolding planks are typically secured using hooks or clips, but due to the complexity of construction sites and variations in crossbar spacing, the locking effectiveness and compatibility of the planks are often difficult to guarantee. Therefore, developing a self-locking, adjustable, anti-slip scaffolding plank locking device is of great significance.

[0003] Currently, common scaffolding platform locking devices typically employ hooks or clips. The hooks are manually secured to the scaffolding crossbars and reinforced with bolts or pins to improve the stability of the connection between the hook and the crossbar. However, these structures largely rely on manual intervention, cannot automatically lock after the hook is attached, and have limited adjustability.

[0004] However, existing technologies have the following problems: when the hooks of traditional anti-slip scaffolding board locking devices are hung on the scaffolding crossbars, they cannot be automatically locked and require additional operation to ensure fixation. This not only increases the operation steps for construction workers, but also leads to insecure locking due to negligence, posing a safety hazard. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides an anti-slip scaffolding pedal locking device, which aims to improve the problem that traditional anti-slip scaffolding pedal locking devices cannot self-lock when the hooks are hung on the crossbars of the scaffolding.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an anti-slip scaffolding pedal locking device, including a hook, a movable groove on one side of the hook, and a locking component inside the hook; The locking assembly includes an L-shaped lock, which is slidably connected inside the hook and inside the movable groove. A limit groove is formed inside the L-shaped lock. A second limit pin is fixedly connected inside the hook. The second limit pin is slidably connected inside the limit groove. A first limit pin is fixedly connected inside the hook.

[0007] As a further description of the above technical solution: A second housing is fixedly connected to one side of the hook, and a first housing is fitted onto the outer wall of the second housing.

[0008] As a further description of the above technical solution: A frame is fixedly connected to one side of the shell, and a scaffold board is fixedly connected to the top of the frame. The scaffold board has anti-slip perforations inside.

[0009] As a further description of the above technical solution: The inner part of the second housing is threaded with a threaded rod, one end of which is rotatably connected to the outer wall of the first housing.

[0010] As a further description of the above technical solution: The outer wall of the threaded rod is threaded with a fixing nut, and one side of the fixing nut is fixedly connected to the inner wall of the housing.

[0011] As a further description of the above technical solution: A limit ring is fixedly connected to the outer wall of the threaded rod, and a nut is fixedly connected to one end of the threaded rod.

[0012] As a further description of the above technical solution: The limiting ring is slidably connected inside the limiter, and one side of the limiter is fixedly connected to the outer wall of the hook.

[0013] As a further description of the above technical solution: A scaffold crossbar is provided on one side of the frame, and the scaffold crossbar is slidably connected to the bottom of the hook.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the L-shaped lock can slide in the movable groove opened on one side of the hook, so that the hook is fastened to the crossbar of the scaffold. The crossbar of the scaffold compresses the short arm of the L-shaped lock. Under the action of compression and gravity, the L-shaped lock slides downward along the limiting pin two through the limiting groove, so that the long arm of the L-shaped lock swings to the bottom of the crossbar of the scaffold. At the same time, the limiting pin one will lock out the short arm part of the L-shaped lock, thus achieving the function of automatic locking when the hook is fastened to the crossbar of the scaffold. This solves the problem that the traditional anti-slip scaffolding pedal locking device cannot self-lock when the hook is hung on the crossbar of the scaffold, and improves the practicality of the anti-slip scaffolding pedal locking device.

[0015] 2. In this utility model, rotating the nut drives the threaded rod to rotate, which in turn drives the fixed nut to move, thereby causing the second housing to move relative to the first housing inside the first housing. This adjusts the relative position of the hook and the scaffold board, achieving the function of adjusting the hook position. This solves the problem that traditional anti-slip scaffolding pedal locking devices are inconvenient to place scaffold boards when locking the crossbars due to errors in the spacing of the erected scaffolding, thus improving the adaptability of the anti-slip scaffolding pedal locking device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3 An embodiment of this utility model provides: an anti-slip scaffolding pedal locking device, including a hook 2, a movable groove 7 on one side of the hook 2, a locking component inside the hook 2, and the movable groove 7 for allowing the locking component to move; The locking assembly includes an L-shaped lock 10, which is slidably connected inside the hook 2 and inside the movable groove 7. A limiting groove 11 is provided inside the L-shaped lock 10. A limiting pin 2 is fixedly connected inside the hook 2. The limiting pin 2 is slidably connected inside the limiting groove 11. A limiting pin 1 is fixedly connected inside the hook 2. When the hook 2 is fastened to the scaffold crossbar 1, the scaffold crossbar 1 squeezes the short arm of the L-shaped lock 10. Under the action of compression and gravity, the L-shaped lock 10 slides downward along the limiting pin 2 12 through the limiting groove 11, causing the long arm of the L-shaped lock 10 to swing to the bottom of the scaffold crossbar 1. At the same time, the limiting pin 1 9 will lock out the short arm part of the L-shaped lock 10, thereby locking the hook 2 onto the scaffold crossbar 1.

[0020] Reference Figures 1-5A second housing 8 is fixedly connected to one side of hook 2, and a first housing 3 is fitted onto the outer wall of the second housing 8. A frame 4 is fixedly connected to one side of the first housing 3. Hook 2 is connected to the frame 4 through the second housing 8 and the first housing 3, and serves to fix the footboard when it is placed. A footboard 5 is fixedly connected to the top of the frame 4. The footboard 5 has anti-slip perforations 6 inside. The frame 4 supports the footboard 5, and the anti-slip perforations 6 on the surface of the footboard 5 can play an anti-slip role to prevent workers from slipping when walking. A threaded rod 13 is threadedly connected inside the second housing 8, and one end of the threaded rod 13 is rotatably connected to the outer wall of the first housing 3. A fixing nut 14 is threadedly connected to the outer wall of the threaded rod 13, and one side of the fixing nut 14 is fixedly connected to the inner wall of the second housing 8. A limit ring 17 is fixedly connected to the outer wall of the threaded rod 13, and a nut 16 is fixedly connected to one end of the threaded rod 13. The limiting ring 17 is slidably connected inside the limiter 15. One side of the limiter 15 is fixedly connected to the outer wall of the hook 2. Rotating the nut 16 drives the threaded rod 13 to rotate, and the limiting ring 17 and the limiter 15 ensure that the threaded rod 13 only rotates radially. When the threaded rod 13 rotates, it drives the fixing nut 14 to move, thereby causing the housing 2 8 to slide inside the housing 1 3, thus adjusting the position of the hook 2 relative to the scaffold board 5 to accommodate errors caused by the erection of the scaffold crossbar 1 and to facilitate the installation of the board. A scaffold crossbar 1 is provided on one side of the frame 4, and the scaffold crossbar 1 is slidably connected to the bottom of the hook 2.

[0021] Working principle: Rotating the nut 16 drives the threaded rod 13 to rotate, which in turn drives the fixing nut 14 to move, thereby causing the housing 2 8 to move relative to the housing 1 3 inside the housing 1 3, thereby adjusting the position of the hook 2 fixed at one end of the housing 2 8, thus adapting to the spacing error of the scaffold crossbars 1 caused during scaffold erection when placing the board, making the placement of the board more convenient and easier.

[0022] After adjusting the position, hook 2 is fastened onto the scaffold crossbar 1. The scaffold crossbar 1 presses against the short arm of L-shaped lock 10. Under the action of pressing and gravity, L-shaped lock 10 slides downward along limit pin 12 through limit groove 11, causing the long arm of L-shaped lock 10 to swing to the bottom of scaffold crossbar 1. At the same time, limit pin 9 will lock out the short arm of L-shaped lock 10, thereby locking hook 2 onto scaffold crossbar 1. When hook 2 needs to be removed, push L-shaped lock 10 along limit groove 11 to disengage limit pin 9 from the short arm of L-shaped lock 10, thereby releasing the lock. At this time, hook 2 can be removed directly.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
